The tweet in question? Here is a screencap of the quickly-deleted message, from Christina Coleman's twitter feed:
This week, survivors of domestic abuse started a pair of hashtags, #WhyIStayed and #WhyILeft, to educate others on the realities of domestic abuse and empower those within harmful relationships. In light of football player Ray Rice's recently-uncovered tapes his subsequent suspension, these words are that much more powerful.
Of course, that's not what DiGiorno thought the hashtag was about, and in their attempt to stay on top of trends on Twitter threw this into the public eye without a care in the world. As you can see, DiGiorno has since apologized for their ignorance. Just another warning message to #Brands on #SocialMedia, right?

By the way, those above tweets are what Domino's considers an official announcement via their social media channels. Because #brands.

The idea is that you'll be able to register your Twitter handle with your existing Domino's pizza account, at which point you can throw a tweet at the Domino's corporate handle. They'll send you an automated direct message, and then BOOM. Pizza to your door.
